The Chinese Have Developed an Amazing “Mist Cannon” to Shoot Pollution From the Sky

By: | December 29th, 2015

China’s economy has grown tremendously, but at a price. Power plants, factories, and industries are all polluting the environment. Although the Chinese government is trying to tackle the issue, some local councils have come up with a brilliant idea to control pollution by using huge mist cannons.

These mist cannons are designed for effective dust control.  These cannons work by pursuing “cloud seeding.”

Pressurized water goes through jet nozzles which turns the water into a fine mist. The mist is dispersed via a strong air flow generated by a powerful fan.

On contact with harmful specks of dust, mist clings to the dust particles. The liquid particles form water droplets that fall to the ground as rain. This way falling raindrops “scavenge” the dust particles from the air.

There are two versions of these fog cannons. One is stationary, and the other one is mobile. Mobile versions can be mounted on a vehicle and can be operated while in motion.

These mist cannons are highly effective: two of the machines eliminated dust from a six-story building’s explosive demolition in about five minutes.
